To all whom it may concern: 1

Be it known that I, CHARLIE C. PALMER, a citizen of the United States,residing at Osce 01a, in the county of Clark and State of Iowa, haveinvented new and useful Improvements in Regulating Means forSelf-Feeders and Band-Cutters, of which the following is aspecification.

This invention relates to improvements in self-feeders and band-cuttersfor threshingmachines, and refers more particularly to the meansemployed for regulating the supply of grain delivered to thethreshing-cylinder.

Theobject of my invention is to provide a structure whereby thegrain-bundles if too freely fed toward the cylinder of the thresherwill'automatically control the power-transmitting means, and therebyonly permit the passage of a maximum amount of grain.

A further object of my invention is to provide afeed-regulatingmechanism thatinthe event the grain be rapidly fed towardthe cylinder to cause the delivery-belt to choke the continued pressurethereon will effect a reversal of said feeding-belt and cause the grainto be entirely removed from theen trance to the carrier leading to thecylinder,

automatically return to its normal movement. In the meantime, however,the motion of the cylinder and itscarrier will notbe afiect'ed;

Many other objects and advantages will be hereinafter referred to and beparticularly tion of my improvement, showing its application. Fig. 2 isa perspective view of the grain-admission-regulating device. a top planView. Fig. 42i$ a detail section on line at 4 of Fig.1. Fig. 5 is adetail section The" same numerals refer to like parts in all thefigures.

1 indicates the receiving end of a threshing-machine having the usualcylinder 2 of any well known construction and being mounted on a shaft3; A frame 4 projects from the thresher andis adapted to carry themechanism for cutting and feeding the grain to the cylinder, togetherwith the parts 00- whichthe friction-pinion 24 impinges. ,pinion 24 isslidably mounted on a shaft 25 of such shape as will materially decreasethe :thrust andreduce the friction of the working parts. The shaft for aportion of its length Fig. 3 is a crank-shaft 13 and the opposite endbeing guided or supported in suitable ways. The inner end of thefeed-carrier is in close proximity to'the cylinder 2, so as to alwayssupply a uniform and constant supply of grain thereto.

Mounted in the frame 4 on a crank-shaft l4 and rocking supports 15 are aseries of forks 16', having amotion in a forwardly and downwardlydirection and adapted to spread the bundles and assist in feeding thegrain to the lower feed-carrier, it being understood any well-knownmeans may be employed to w cut the bundles of grain.

The mechanism thus far described relates more particularly to what issubstantially common in the art and only constitutes features with whichmy invention coacts.

Mounted in bearings 20 on the framed is a shaft 21, carrying asprocket-wheel 22 and a friction-wheel 23, the latter being beveled outslightlyto form a bearing-surface against The is in cross-sectionapproximatelya Maltese of corresponding size and shape." Toreduce thefriction to a minimum,the pinion 24 is provided with anantifriction-rolleri'25 for each wing of the shaft 25, which makes theparts connected to said roll extremely sensitive in operation. On oneend of the shaft 25 is fixed a worm 27, meshing with a wormgear 28 onthe shaft 6. Hence motion to the extension-belt is imparted from thefrictionwheel 23.

On a rocking shaft 29, mountedabove the cross, and the pinion 24. has anopening 26 rear end of the extension carrier, are a series of dependingfingers 30, the lower end being of such distance from the belt as willpermit the passage of a predetermined amount of grain before they areoperated. A crankarm extends from one'end of the shaft 29 and isconnected by a link 31 to an upright lever 32, pivoted to the frame at33 and havsprocket-Wheel 35 on the crank-shaft 14, communicates a directand constant rotary motion to the friction gear 23 and to the shaft 13through the medium of the sprocket-wheel 36.

From the foregoing description it is thought the operation of myinvention will be readily understood by those skilled in the art towhich it appertai-ns. Motion is imparted to the shaft 14 from the wheel39, imparting a kicking-forward movement of the forks, revolving thefriction-gear 23, imparting a forward movement to the lowerfeed-carrier, revolving the friction-pinioncarrying shaft 25, and thefeed extension-belt. The bundles of grain are now delivered to theextension-belt and they are carried up and subjected to the action ofthe forks 16 to be equally spread over the lower feed-carrier. As beforestated, the fingers 30 are of such height from the belt as will onlypermit a certain amount of grain to pass without imparting a rockingmotion to the rock-shaft. Should, however, more grain be delivered tothe carrier than can be acted on by the thresher-cylinder, it will forcethe fingers 80 in and rock the shaft 29, which movement will draw thefrictionpinion 24 toward the center of the frictiong'ear 23, which byreason of the extensioncarrier receiving its motion through this pinionthe advance movement of the grain will be reduced and accordingly theamount of grain delivered to the lower feed-carrier. If the excess of.grain continues to accumulate in front of the fingers 30, the shaft 29will continue to rock, whereupon the movement of the friction-pinion 24: is continued and will eventually pass to the opposite side of thecenter of the friction-gear, imparting a reverse motion to saidfriction-pinion, and necessarily to the extension feed carrier. However,the movements of the forks, friction-gear, and the cylinder areuniformly the same.- The reversing of the belt will naturally unload thegrain, and when a sufficient quantity has been removed and the pressureof the grain against the fingers relieved the coacting levers will bringthe friction-gear to its normal position and again the feed-belt willfeed the grain toward the cylinder. The weight of the fingers 30 and.the cooperating ing-cylinder, a friction-gear, gearing which isconstantly in contact with the friction-gear for communicating motionfrom said frictiongear to the feed-belt, and levers connected to saidgearing for communicating motion from the gear to the frictionfeed-belt, in proximity to the belt'for effecting the reversal of themotion of said belt, when it carries more than a predetermined supply ofgrain, substantially as described.

A machine for the purpose specified,com-' prising a frame, afeed-belt, a thresher-cylinder, a shaft, a beveled friction-pinion onthe shaft adapted to move lengthwise thereon, a beveled friction-gear, alever located in proximity to said feed-belt, and a second. leverconnected to the first-named lever for moving vthefriction-pinion'toward and past the center of the friction-gear, tofirst stop and then reverse the movement of the feed-belt when thelatter carries more than a predetermined supply of grain, substantiallyas described.
